Currents (A Dc And Ac) - Chauvin Arnoux C.A 5003 Manual De Empleo

5 - DC AND AC CURRENTS
Always switch off the circuit to test before connecting the
multimeter to the circuit. If the "Fus." light comes on, change the
faulty fuse(s) (Reminder: minimum voltage of 100 V).
Connect the leads to the multimeter and connect in series to the
circuit with:
- the red lead in the "mmA" terminal, up to 1.5 mA
- the red lead in the "15 A" terminal, from 1.5 A to 15 A
Switch off the power supply to the circuit before changing range.
When the order of magnitude is not known, place the switch on the
highest range then progressively lower to the appropriate range.
To get the current in mA, mA or A, multiply the value read on the
appropriate scale by the reading coefficient shown in the table.
